IMPROVEMENT IN FLTING-MACHINES.

Moro- The Schedule referred to in these Letters Patent and making part of the same To Hicham-il may concern.:

,Be it known that I, MARY 1. Cani-ENTER, of the citfyand county of San Francisco, and State of California, have invented an Improvement in Flirting- Machines, and .l do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawing and to the letters marked thereon.

My invention refers to certain improvements in that class of Tinting-machines in which the cloth or fabricopcratcd upon is passed between hot cylindrical toothed rollers; and consists of certain details of construction, hereinafter described, and has for its objecteconomy in labor and fuel, and cleanliness in heating the toot-hed cylinder, and, also to provide a machine .that can be made to perform diiiercnt kinds of work by changing the cylinders. I i

In the drawing that forms a. part of this specification- Figure 1 represents a perspective view of `the complete machine.

Figure 2 is a. side elevation, with cci-tain parts removed and other par in section.

Figure 3 is a vertical longitudinal section.

Like letters refer to like parts.

a a' are hollow toothed cylinders.

b b are cylindrical shafts, to which the cylinders are Yloosely iii-ted.

'opcningmay b e closed by the damper 7.2.

l is a 'spring for holding the furnace-top down.

I1n is a spring for forcing the furnace-top d'upwhere the strain on the spring l is relaxed, by unscrewing the nut n of the adjustable rod o.

p p are adjustable screws.

The cylinders a a.' are retained in their positions on the shafts 7; b by the sliding plates q q, fitting loosely to grooves, -r r, in the cylinders. ly removing the plates q q, the cylinders a a can bc readily taken ott, and replaced by others, as required.

lhc shaft 7)' docs not revolve, but passes through, and is rivctcd fast to the furnace c.

'1`hc shaft 71 is caused to revolve by turning thc crank s, which has its bearings in thc furnace-top (l, and, by means of the feather and groove t, causes the cylinder a to revolve, which comn'rnnicatcs motion to the cylinder af.

The furnace-top d is 'hinged to the furnace by means of a rod, n, parallel with thc shafts b b. The nlimnncnt. ot' this shaft is still further secured by means of the adjustable screws ,p p, rod o, nut n, and spring l. The shafts b b are made of copper or other good conductors of heat, and the heat of the furnace is conveyed through then), by conduction, to the cylinders a a', but one or both of these shafts maybe made hollow, with the ont-er end closed, and arranged -in such amanner as to causen. draught of flame and hot gases to pass tln'oughthem.

The furnace c may be heated by charcoal, a gas-jet or lamp, or in any other convenient manner. The cylinders a a may have any desired number of teeth, for large or small flirting, or not any teeth, in which case they become smooth cylinders, and may be `used in ironing articles that do not require flutinen After the cylinders (t a have become sufficienti y hot, the fabric to be operated on is placed between them, and then, by turning the crank s, the cylinders are caused to revolve, and the fabric, bypassing between them, is caused to assume a shape corresponding to the teeth of the cylinders used,

In `ilating-machines' of this class not 'having my improvements, the toothed cylinders being made in one piece with and forming a part of their respective shafts, and the removal or exchange of these shafts being attended with great difficulty and inconvenience,

it has always been `impracticable to do more than one kind of uting with each machine, and it has been necessary to have as v many complete machines as there are different kinds of fiuting to do; it is evident-that my invention obviates this difficulty. l

In machines, hereinbefore mentioned, not having my improvements, the heat is obtained by placing hot irons, rods, or bolts in the shafts, made hollow for that purpose, and the heating and changing of these rods or bolts is a source of much annoyance and in'- convenience. l v

In other n'iachines, also, both the upper and lower shafts revolve, manifestly making their alignment and adjustment much more diiiicult than in my improved machine, where the shaft b is fixed.

It will also be seen that, notwithstandimr my invention combines so many improvements, 1t is exceedingly simple in its construction, and not-liable to get out of repair.

Having thus described my invention,

What I claim, and desire to secure by LettcrsPatent, is-

1. The adjustable rod o, nut n, the springs l m, `and the adjustable screws 1) p when combined with the lid, and arranged and operated as described.

2. The cylinders a a, the shafts 11 b', the feather and groove t, the furnace c and furnace-top d, the shields e c and linings fj, the sliding plates q q and the grooves 1' r, rod o, nut n, springs l m, and screws p p, combined, substantially as described.

1n testimony whereof I have hereunto set my hand and seal.
